Sender-based ranking of person profiles and multi-person automatic suggestions

ABSTRACT

Systems and methods for searching of information regarding persons or to provide assistance for completion during address input. In one embodiment, a method includes automatically generating profiles for persons identified in messages, such as outgoing emails. Based on how the addresses of the persons are used in outgoing messages, the relevancy scores of the addresses are determined. When a user is searching for information or typing an address, the profiles and the relevancy scores are used to identify and sort search results or suggestions for the completion of the address input.

FIELD OF THE TECHNOLOGY

At least some embodiments of the disclosure relate to user interfaces in general and, more particularly but not limited to, user interfaces for searching of information regarding persons or initiating a communication, such as composing an email message or a text message, or dialing a phone call.

BACKGROUND

Many systems and applications have been developed to allow people to communicate with each other. Such systems and applications may provide communication via emails, instant messages, text messages, web/online postings, etc. Email systems typically use servers to receive the electronic messages from the senders, to store and/or forward the messages on behalf of the senders, and to deliver the messages to the recipients. Since the servers can store the messages for a period of time before delivery, a recipient and a sender do not have to establish a direct communication connection to facilitate the transmission of the electronic message. Thus, the sender and the recipient do not have to be online simultaneously for email communications.

In an email system, an email client application is typically used to receive and display messages and to compose and send messages. The email client application communicates with one or more email servers to receive and send messages. Email addresses are used to identify the recipients of the messages.

An email client application may be a stand alone application running on a user terminal (e.g., a personal desktop or portable computer, a personal digital assistant (PDA), or a smart phone). The email client application stores messages received from one or more email servers, and can display the stored messages to a user even when the user terminal is not connected to the network.

An email client application may also be implemented in part via a server. The server stores the messages on behalf of a user, and when requested, formats a message as a web page for display on a browser used by the user.

Instant messaging (IM) allows real-time communication between people. A communication connection between the devices of the participants in an instant messaging session is required for the delivery of the instant messages sent during the session. User names are typically used to identify the online presence and thus the online addresses (e.g., Internet Protocol (IP) addresses) of the users, which are used to establish the communication connections for the instant messaging session. Therefore, the user names of instant messaging systems can be considered as the addresses for establishing online connections for instant messaging sessions, from the point of view of the users.

Text messaging allows users to communicate via mobile phones over a cellular communications network. Text messages are typically transmitted via Short Message Service (SMS) or Multimedia Messaging Service (MMS). The phone numbers of the mobile phones are used as the addresses of the recipients of the text messages.

Some user terminals (e.g., personal computers, PDA, mobile phones) may support communications in multiple modes, such as email, instant messages, and text messages.

Some applications have been developed to organize address information for users. For example, an address application may store information about a plurality of persons. For each of the persons, the address application may store the name of the person, the email address of the person, the street address of the person, the IM address of the person, the web page address of the person, phone numbers of the person, etc.

SUMMARY OF THE DESCRIPTION

Systems and methods are provided for searching of information regarding persons or to offer assistance for completion during address input. Some embodiments are summarized in this section.

In one embodiment, a computer-implemented method includes: receiving a search request or an incomplete input from a user; and presenting, via a user terminal, a plurality of results in response to the search request or the incomplete input, wherein the plurality of results is presented in a ranked order based on usage of a first messaging account of the user to compose a message, the first messaging account being one of a plurality of messaging accounts of the user, and the ranked order being further based on profile data, the profile data comprising a profile for each of a plurality of persons, each respective profile including at least one address (or in alternative embodiments, at least two addresses) associated with the respective person, and the profile data being related to persons or addresses used in messages to or from the user terminal.

In another embodiment, a computer-implemented method includes: scanning, by a computer, a set of messages of a user to identify a plurality of addresses (note that in alternative embodiments, even more generally a set of communications or communication events of any type or mixture of types may be scanned including, for example, e-mails, instant messages, text messages, phone calls, etc.); identifying, by the computer, names of persons at the addresses to generate a plurality of profiles for the persons, each profile of the plurality of profiles comprising a name of a respective person, and at least one address (or in alternative embodiments, at least two addresses) for the respective person; computing, by the computer, scores of the persons using data in the plurality of profiles to determine relevancy of the persons to the user; and sorting the set of persons based at least in part on the scores.

In another embodiment, a computer-implemented method includes: scanning, by a computer, a set of messages of a user to identify a plurality of addresses; identifying, by the computer, names of persons at the addresses to generate a plurality of profiles for the persons, each profile of the plurality of profiles comprising a name of a respective person, and at least one address (or in alternative embodiments, at least two addresses) for the respective person; computing, by the computer, scores of the persons using data in the plurality of profiles to determine relevancy of the persons; sorting the set of persons based at least in part on the scores; receiving input from the user in a recipient name or address field of a message; and subsequent to the receiving input, presenting to the user, in an order determined by the sorting, one or more suggestions for an additional recipient name or address to add to the message.

The disclosure includes methods and apparatuses which perform these methods, including data processing systems which perform these methods, and computer readable media containing instructions which when executed on data processing systems cause the systems to perform these methods.

Other features will be apparent from the accompanying drawings and from the detailed description which follows.

DETAILED DESCRIPTION

The following description and drawings are illustrative and are not to be construed as limiting. Numerous specific details are described to provide a thorough understanding. However, in certain instances, well known or conventional details are not described in order to avoid obscuring the description. References to one or an embodiment in the present disclosure are not necessarily references to the same embodiment; and, such references mean at least one.

Reference in this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosure. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Moreover, various features are described which may be exhibited by some embodiments and not by others. Similarly, various requirements are described which may be requirements for some embodiments but not other embodiments.

In one embodiment, a user terminal is configured to provide assistance for the completion of inputting an address. While the user is typing to provide an input to specify an address for a message, the user terminal uses the incomplete input that has been provided to an address field so far by the user to identify one or more options or suggestions to complete the input, and thus allows the user to complete the input by selecting one.

In one embodiment, the user terminal is configured to search a profile set to search for a portion of the candidates that matches the incomplete input provided by the user. The profile set contains information about a plurality of persons, to whom the user may or may not have previously sent a message.

FIG. 1 shows a user terminal to provide assistance in address input according to one embodiment. The user terminal may be implemented as a personal computer, a web enabled television set, a personal digital assistant (PDA), or a mobile phone, using special purpose hardware (Application-Specific Integrated Circuit (ASIC) or Field-Programmable Gate Array (FPGA)), software and a general purpose processor, or a combination of special purpose hardware and software. Thus, the disclosure is not limited to a particular implementation.

In FIG. 1, the user terminal (101) is configured to store the messages (115) received at the user terminal (101) and the messages (117) sent from the user terminal (101). The user terminal (101) includes a message viewer (123) which can be used to display a message selected from the received messages (115) or selected from the sent messages (117).

In FIG. 1, the user terminal (101) further includes a message composer (121) which is configured to present a user interface to facilitate the composition of an outgoing message.

In one embodiment, the user terminal (101) is configured to generate an address set (111) based on the addresses that have been specified in the message composer (121) for one or more previously sent messages (117). When an address is used in the message composer (121) to specify a recipient of a message, the address is added to the address set (111), if the address is not already in the address set (111).

In one embodiment, the message composer (121) uses the address set (111) to suggest candidates for the completion of an input when the user is typing an address. For example, when the characters typed in an address field are the same as the first characters in a number of email addresses in the address set (111), the message composer (121) displays the email addresses as possible candidates for the completion of the input.

In one embodiment, the user terminal (101) further includes a profile presenter (125), which can provide suggestions for completion based on the profile set (113) maintained by the profile builder (119).

In one embodiment, the profile builder (119) is configured to extract profile data of various persons based on the received messages (115) and the sent messages (117). The profile builder (119) can extract information about persons not only from the headers of the messages where the senders and the recipients of the messages are specified, but also from the bodies of the messages and from other online sources, such as online directories, social networking websites, web pages, result pages found by search engines, etc.

Since the profile builder (119) obtains the profile data for various persons referenced in the messages (115 and 117), the profile set (113) is more comprehensive than the address set (111).

In one embodiment, the profile builder (119) is configured to scan the received messages (115) and the sent messages (117) for email addresses and names associated with the email addresses. The profile builder (119) generates a profile for each person identified to create the profile set (113). When new messages are received or sent, the profile set (113) is updated based on the new messages.

In some embodiments, the profile builder (119) may further identify persons based on scanning the received messages (115) and the sent messages (117) for phone numbers, names, addresses, etc.

In some embodiments, some or all of the components (111-125) in the user terminal (101) may be hosted on a server remote to the user terminal (101) (e.g., accessible via a website and a web browser). For example, in one embodiment, the received messages (115) and the sent messages (117) may be hosted on a web site; and the user can use a web browser to view a selected one of the messages (115 and 117).

For example, the profile builder (119) may be configured to communicate with the server to extract the profile set (113) from the messages (115 and 117) hosted on the server. Alternatively, the profiler builder (119) may also be hosted on the server to build the profile set (113) on the server.

FIG. 2 illustrates a profile of a person according to one embodiment. In FIG. 2, the profile (131) includes various fields, such as the name (141) of the person, a photo image (142) of the person, one or more phone numbers of the person (143), address information (144) (e.g., email address, IM address, street address), business information (145) (e.g., employer, work address, job title), the date and time of the last message received from the person (146), the date and time of the last message sent to the person (147), the total number of messages received from the person (148), the total number of messages sent to the person (149), etc.

In one embodiment, the profile builder (119) obtains at least some of the information for the fields from the received messages (115) or the sent messages (117) to identify the person, and then uses other information sources to obtain the data for the other fields in an automated way to collect the profile information on behalf of the user.

For example, the profile builder (119) may use social networks, search engines, photo services, etc. to obtain the photo (142), the business information (145), etc.

FIG. 3 illustrates a system to obtain data for a profile according to one embodiment. In FIG. 3, under the control of the profile builder (119), the user terminal (101) may communicate with various servers in an automated way to extract data for the profile (131) over the network (151). The network (151) may include a local area network, a cellular telecommunications network, a wireless wide area network, a wireless local area network, a wireless personal area network, an intranet, and/or Internet.

In one embodiment, the user terminal (101) communicates with the message server (162) to receive and send the messages (115 and 117).

In one embodiment, after the profile builder (119) extracts from the messages (115 or 117) certain information (e.g., an email address, an IM user name, a phone number, and/or a name) about a person, the profile builder (119) uses the extracted information to query various servers to obtain further information (e.g., photo (142), phone number (143), address information (144), and/or business information (145)) about the person to create the profile (131).

For example, the user terminal (101) may query a web search engine (163), an online directory (164), a social network server (165), a business website (166), a personal website (167), a media sharing website (168), a map and direction web site (169), an online retailer (152), a travel website (153), a location website (155), and/or other servers. Information that can be used as search criteria include names, screen names, social network profile names, social network profile URLs, physical addresses, website URLs, email addresses, or telephone numbers. Information that is collected as a result of these queries may be used in future searches to identify additional information that may be used to create a person profile.

For example, the user terminal (101) may receive an email sent by a person via the message server (162). The profile builder (119) of the user terminal (101) is configured to perform a search using the web search engine (163) with the email address of the person as the search criteria. The search engine (163) may return a search result that includes the phone number (143) of the person. The profile builder (119) extracts the phone number (143) from the search result and stores the phone number (143) as part of the profile (131) of the person. The search engine (163) may also return the URL for or link to a personal website (167) belonging to the person. The personal website (167) may contain additional information about the person that may be used to create a person profile, such as additional contact information or biographical information.

In another example, the email address belonging to the person may include an extension (or domain name) for a company. The profile builder (119) of the user terminal (101) is configured to perform a search using the search engine (163) with the email extension (or domain name) as the search criteria. A result returned by the search may be a business website (166). The profile builder (119) of the user terminal (101) is further configured to search the business website (166) to obtain information relevant to the profile (131) of the person. For example, a web page on the business website (166) may contain additional information about the person that may be used to create a person profile, such as business information (145), additional contact information or biographical information.

In another example, the profile builder (119) of the user terminal (101) is configured to perform a search using an online directory (164) (e.g., a person search directory, a yellow page directory) with the name (141) of the person or other contact information as the search criteria. The online directory (164) may return search results that include additional contact information and other information that may be used for the profile (131) of the person.

In another example, the user terminal (101) may receive an email sent by the person via the message server (162). The email may contain a social network user name for the person. The profile builder (119) of the user terminal (101) is configured to extract this social network user name from the email and use it to access the social network server (165). A webpage on the social network server (165) may contain additional contact information and other information that may be extracted and used by the profile builder (119) to create the profile (131) of the person. The webpage on the social network server (165) may also contain additional contacts that may be associated with the person in the profile (131). For example, persons on the friends list of the webpage on the social network server (165), or persons who have posted comments or messages on the social network server (165) may be listed as contacts in a contact network for the person.

In another example, a search performed using the search engine (163) may return a URL or link for a media sharing website (168) (e.g., for sharing photos or videos). The media sharing website (168) may store profile information about the person. Thus, the profile builder (119) of the user terminal (101) can extract additional contact information or biographical information from the media sharing website (168) for the creation of the profile (131) of the person. For example, a profile belonging to the person on a video sharing website may include an instant message screen name (user name) for the person. This screen name may be extracted and displayed as part of the profile (131) of the person.

In one embodiment, information extracted from communications between the person and other users may also be used to update profile information on a social network server (165) or other websites. For example, the profile builder (119) of the user terminal (101) may detect that the person has primarily used email address “david@foo.com” in recent communications, whereas the profile of the person on the social network server (165) shows his email address as “david@bar.com.” The profile builder (119) of the user terminal (101) can share the new email address of the person with the social network server (165) to allow the social network server (165) to automatically update the corresponding information about the person, or to suggest the person to make an update based on this changed behavior detected by the profile builder (119) of the user terminal (101).

In one embodiment, the profile builder (119) of the user terminal (101) can also extract information about the person from the travel website (153) and the online retailer (152) for the creation of the profile (131) of the person. For example, after an email containing information about a flight itinerary is received in the user terminal (101), the profile builder (119) of the user terminal (101) may extract a flight number or other information about a flight from the email. The profile builder (119) of user terminal (101) then queries the travel website (153) using the flight number or other flight information as search criteria. Information about the flight, such as the destination city or the departure city, expected departure time, expected arrival time, expected delays, weather in the destination city, weather in the departure city, or any changes to the flight may be used as part of the profile (131) of the person.

In another example, an email containing information about an item or service that the second user is interested in purchasing may be received in the user terminal (101). The profile builder (119) of user terminal (101) is configured to query one or more search engines, websites, or on-line retailers (152) to determine which retailer or website has the best price or currently has the item in stock or the service available. This information is extracted by the profile builder (119) and displayed by the profile presenter (125) as part of the profile (131) of the person.

In one embodiment, the profile builder (119) of the user terminal (101) can also extract information from a map and direction website (169) and location servers (155) as part of the profile (131) of the person. For example, the person may own a GPS unit, cell phone, or other device that is capable of transmitting the person's current physical location to the location server (155), which allows other users to access the person's current location information. If the user of the user terminal (101) has permission to view the location information of the person, the profile builder (119) of the user terminal (101) may access the location server (155) over the network (151) to receive location information about the person. This location information can be displayed as part of a person profile.

The profile builder (119) of the user terminal (101) may also access the map and direction website (169) to create a map of the current location of the person, or to generate directions to the current location of the person. The map or directions may be displayed by the profile presenter (125) as part of the profile (131) of the person. The map and direction website (169) may also be used to generate a map or directions to one or more known street addresses of the person, such as a work address or home address. The map or directions can be displayed by the profile presenter (125) as part of the profile (131) of the person.

FIG. 4 illustrates a user interface to provide assistance in address input according to one embodiment. In FIG. 4, the user interface (201) is configured for composing an outgoing message. The user interface (201) includes entries to specify the addresses of the recipients of the message. For example, the entry box (203) is configured to receive the email address of an outgoing email, which may be sent from the user terminal (101) via the message server (162).

In one embodiment, when the entry box (203) detects a change in the content received in the entry box (203) (e.g., a keystroke is received in the entry box (203), as the user types a letter on a keyboard to provide an input), the profile presenter (125) determines a set of suggestions for the completion of the input in the entry box (203). The profile presenter (125) uses the incomplete input in the entry box (203) as a search criterion to find from the profile set (113) a set of suggestions for the complete address input. The suggestions are presented in the window (205) as a selectable list.

In one embodiment, when the message composer (121) has an existing, native mechanism for displaying suggestions (e.g., making suggestions based on address set (111)), the profile presenter (125) can be configured as an add-on module to display these suggestions as well and to hide the native mechanism of the message composer (121) for displaying suggestions.

In FIG. 4, the item (209) on the top of the list is highlighted; and the user may select the highlighted item (209) with a keystroke (e.g., pressing Tab key, Enter key, Home, End, PgUp, PgDown, etc.). The user may use the arrow keys to move the highlight up or down the list to highlight a different item, or provide additional input in the entry box (203) to cause the profile presenter (125) to update the suggestions in the window (205). The user may also use the cursor (207) to select an item using a cursor control, such as a mouse, a track ball, a touch pad, a touch screen, etc.

In one embodiment, when the message composer (121) has an existing, native mechanism that uses these keys for the display of suggestions, the profile presenter (125) configured as an add-on module can hide these keystrokes from the native mechanism.

In one embodiment, after an item is selected from the list presented in the suggestion window (205), the address represented by the item is inserted by the profile presenter (125) into the entry box (203) to replace the corresponding portion that is used to suggest the selected item; and the suggestion window (205) is closed automatically.

In some embodiments, the message composer (121) may be configured to perform post-processing, such as name checking, on the inserted text in the entry box (203) a few moments after the text has been inserted. The insertion by the profile presenter (125) is performed in a way that allows such post-processing by the message composer (121) to continue functioning. For example, if the message composer (121) loses focus or activation, it starts post-processing the entries in the textbox. The profile presenter (125) is configured to temporarily prevent this from happening while the suggestion window (205) is visible and causes this to happen when the suggestion window (205) is closed. To hide the suggestion window (205), the suggestion window (205) is configured as a topmost window that is initially not activated. The Outlook textbox window is subclassed via a code-injection mechanism to temporarily preventing it from getting “kill focus” messages (e.g., through intercepting such messages, and then throwing them away). After the suggestion window (205) becomes invisible, the profile presenter (125) sets the focus back to the textbox window and causes the post-processing to be performed.

For example, in FIG. 4, the incomplete input “Graf” is received in the entry box (203). The cursor “|” in the entry box (203) indicates the insertion point for subsequent keystrokes received in the user terminal (101). While the entry box (203) is expecting additional input from the user, the profile presenter (125) uses the incomplete input “Graf” to identify a set of suggestions, such as mgraf@gmail.com for Mary Graf, ericg@yahoo.com for Eric Grafstrom, graffiti@hotmail.com for Steve Curtis, graffiti@pacbell.net for SFPD, etc., based on the profile set (113) established by the profile builder (119).

In one embodiment, the suggestions are identified by matching the incomplete input with names, addresses and/or other profile data of the persons in the profile set (113). The incomplete input may match the beginning of a last name, the beginning of a first name, the beginning of the name of an organization, the beginning of a domain name of an email address, the beginning of the top level domain name of an email address, the beginning of the email prefix, the beginning of a word in the job title (or the beginning of the job title), the beginning of the city of the person, etc. In some embodiments, when an email prefix contains one or more separators, such as “_” or “.” or “−”, the email prefix is broken down into segments or chunks; and the incomplete input may match the beginning of any of the segments or chunks. When there is a match, the person can be selected as a candidate for the suggestions. Thus, the searching for a match is not limited to matching the beginning of an address that the user has previously typed for a previous outgoing message.

In FIG. 4, the top item, mgraf@gmail.com for Mary Graf, is highlighted and can be selected by pressing the Tab key or the Enter key. Alternatively, the user may select the second item, ericg@yahoo.com for Eric Grafstrom, by pressing a mouse button while the cursor (207) is over the second item. The profile presenter (125) is configured to use the selected address to replace the incomplete input “Graf” received in the entry box (203).

In FIG. 4, if the user further types a letter “f”, the profile presenter (125) will use the incomplete input “Graff” to eliminate some suggestions (e.g., mgraf@gmail.com for Mary Graf, ericg@yahoo.com for Eric Grafstrom) and update the list in the suggestion window (205).

Thus, the profile presenter (125) uses the profile set (113) to identify suggestions based on incomplete input provided in the entry box (203) and to allow the user to select a suggestion to complete the input.

FIG. 4 illustrates an example in which the suggestion window (205) is presented to provide suggestions for the completion of an address input in the “To” field of the user interface (201) for composing an outgoing message. Similar suggestions can be provided when the user is typing in other fields that are configured to receive address inputs, such as the “CC” field, or “BCC” field, of a user interface for composing an outgoing email message. Further, the suggestions can be provided when the user is typing in other types of user interfaces that are configured to receive address inputs, such as a user interface to edit a contact entry, a profile page, etc. Thus, the invention is not limited to the user interface for composing an email message.

FIG. 5 illustrates another user interface to provide assistance in address input according to one embodiment.

In FIG. 5, the suggestions are presented as two parts. The part above the separator (211) is identified from the address set (111) and the part below the separator (211) is identified from the profile set (113).

In one embodiment, the address set (111) is generated by collecting the addresses that have been previously specified in the address fields of the message composer (121) of the user terminal (101). In one embodiment, the suggestion above the separator (211) is identified by matching the incomplete input “Graf” with the starting letters of the addresses in the address set (111). The addresses in the address set (111) that have the leading characters “graf” are selected to generate the suggestions above the separator (211).

In one embodiment, the message composer (121) has an existing, native mechanism for displaying suggestions (e.g., making suggestions based on address set (111)). The profile presenter (125) is configured to obtain the suggestions from the native mechanism (e.g., via scraping, inspecting, querying, etc.) and displays the suggestions above the separator (121).

In one embodiment, the suggestions presented above the separator (211) are identified by the message composer (121). The profile presenter (125) obtains the suggestions from the message composer (121), presents the suggestions in the suggestion window (205), hide the suggestions the message composer (121) would have shown (and thus prevents the message composer (121) from presenting the suggestions in a separate window).

In another embodiment, the profile presenter (125) shows the suggestions based on the profile set (113) in one suggestion window; the message composer (121) shows the suggestions in a different suggestion window; and the profile presenter (125) aligns its suggestion window with the suggestion window of the message composer (121) so that the two suggestion windows appear like two panels of a large window. Alternatively, the profile presenter (125) presents its suggestion window over the suggestion window of the message composer (121) (to cover up and thus effectively disable the suggestion window of the message composer (121)). In one embodiment, the profile presenter (125) causes the suggestion window of the message composer (121) to be invisible on subsequent invocations to hide the suggestion window of the message composer (121).

In another embodiment, the profile presenter (125) uses the address set (111) to identify the suggestions presented above the separator (211) in the suggestion window (205), using the same approach the suggestion window of the message composer (121) would use.

In one embodiment, the profile presenter (125) includes an auto suggest manager. The auto suggest manager can turn on or turn off the feature of auto suggestions generated based on the profile set (113) in accordance with the preferences of the user. The auto suggest manager provides encapsulation, providing an easy interface for external applications to use the auto suggest feature without understanding its implementation. It provides a mechanisms to add the auto suggest feature to a new window (message, contact, etc.), to “clean up” or remove the auto suggest feature from a window or all windows, to allow logging of auto suggest state and problems, and to determine any special preferences the user may have set in the native client (e.g., Outlook).

In one embodiment, the profile presenter (125) includes a suggestion window (205) that presents a dialog box or a list box to show the suggested results. The profile presenter (125) includes a view controller to show or hide the suggestion window (205). The view controller also positions the suggestion window (205) in the correct location (which varies as the user types in text), participates in “hiding” the suggestion window (205) from the native application (e.g., Outlook) so that the native application is not aware of the existence of the suggestion window (205), and notify other modules of navigation commands (PgUp, PgDown, etc.) and user selections. When a selection or keyboard command (e.g., arrow keys, tab return) related to the suggestions occurs, the suggestion window (205) (or a keyboard hook or the inspector controller, discussed below) provides messages to the view controller for processing.

In one embodiment, the profile presenter (125) further includes a result controller, which decides what results to show and when. After the profile presenter (125) detects that the user is typing in an address field (e.g., To, CC, or BCC fields of a window to compose an email), the result controller uses the incomplete input as a search criterion to search for the suggestions based on the profile set (113) and/or based on the address set (111). The view controller causes the display of the suggestion window (205) to show the search results. If the user selects a suggestion from the window (205), the address corresponding to the user selection is put into the address field.

In one embodiment, the profile presenter (125) is implemented as an add-on module for an existing communications client, such as Microsoft Outlook, which can make suggestions by selecting from the address set (111) the email addresses that start with the incomplete input typed by the user in the address field. The suggestion window (205) of the profile presenter (125) subclasses the suggestion window of the existing communications client; and the profile presenter (125) hides the suggestion window of the existing communications client and creates a keyboard hook as well as a subclass mechanism using code-injection to intercept keyboard messages and other messages sent to the hidden suggestion window of the existing communications client to prevent it from processing these keys (e.g. PgUp, PgDown, Tab, Return), and also to cause it to process fake keystrokes or other messages (e.g. to implement “delete” functionality”). In one embodiment, the keyboard hook is a global WH_KEYBOARD_LL hook; in another embodiment, the keyboard hook is a WH_KEYBOARD hook. In one embodiment, the profile presenter (125) creates only one such keyboard hook per thread (especially for the WH_KEYBOARD hook).

In one embodiment, the result controller is configured to handle a rapidly typing user, by stopping a previous search and then starting a new search. For example, if a search for suggestions is started based on the initial input “er” and before the suggestions are displayed the user further typed “ic” to provide the input “eric”, the result controller stops the search for suggestions based on “er” and starts a new search for suggestions based on “eric”.

In one embodiment, an inspector controller is used to hook the functionalities of the profile presenter (125) with the existing communications client, which may be the message composer (121) in one embodiment. When a window for the message composer (121) is constructed and shown, the inspector controller determines whether the user is typing in a field (e.g., entry box (203)) that is configured to receive an address. If the user is typing in an address field, the inspector controller instantiates a keyboard hook to obtain what the user types in the address field to allow the profile presenter (125) to generate the suggestions based on the profile set (113).

In one embodiment, the inspector controller determines if the window should have auto suggest functionality. Read-only windows or unsupported type of windows should not have the auto suggest functionality. The inspector controller then searches for suitable textboxes (using a “Control Calculation mechanism”) that should have auto suggest functionality attached to them. Since the native client (e.g., Outlook) has many configurations (“use Word Editor”, use “RTF Editor”, etc.), different mechanisms are used and a fallback mechanism in case the initial search for a suitable window fails, and in some cases, additional code injection is required because the native client (e.g., Outlook) uses a different process for different windows. The inspector controller uses a “SetProp” mechanism to “remember” which windows have already been subclassed so that auto suggest functionality is correctly added to the newest window. Additionally, the inspector controller keeps track of which textbox (To, Cc, Bcc, etc.) the user is currently using. The inspector controller also is responsible for putting the user's selection (from the dialog) into the selected textbox control. The inspector controller also watches for various windows message in the various subclassed windows (e.g. Activation, Focus, Keyboard), “hiding” (or “eating”) some of these message from the native client (e.g., Outlook) so as not to break other existing functionality of the native client (e.g., Outlook), and using others to notify the view controller that it should hide or show or change the suggestion window (205). In addition to the subclass of the “TextBox” and “Outlook AutoSuggest” window, the main composer window is subclassed as well, and may subclass others in the future. Note that this subclassing mechanism is implemented using code injection and could in the future also be implemented using other mechanisms. Code injection “injects” our code into another program (e.g. Outlook or Word) while it is running.

In one embodiment, the inspector controller subclasses the textbox (and also the parent window) into which the user is typing to receive the keys typed by the user, generate requests for new suggestions in response to keys typed by the user, scroll through the suggestions (e.g., when the user presses arrow keys), indicate a selection by the user (e.g., when the user presses Tab or Enter key) (some embodiments use subclass, some embodiments keyboard hook), the profile presenter (125) hide these keystrokes from the native client (e.g., Outlook window) (by “eating” or consuming the messages), and hide the suggestion window (205) when the keyboard focus is moved out of the textbox or user has activated another application or user has finished selection. The inspector controller instantiates the view controller to process the user input and subclasses the suggestion window of the message composer (121) to create the suggestion window (205). The inspector controller (or the keyboard hook) contacts the view controller to process the user inputs when various keys are received in the textbox in which the user is typing.

In one embodiment, a window driver is used to work with the message composer (121) to obtain current caret position (the position of the text insertion point indicator). In response to the requests from the inspector controller and the suggestion window (205), the window driver may selectively block messages from being passed on to other windows. When a selection is made, the window driver is configured to replace the incomplete input in the address field with the address corresponding to the selection.

In one embodiment, the profile presenter (125) is implemented as an add-on module to a native client, such as Outlook. The Outlook textbox windows are in some cases “rich edit controls” which allow other controls to be embedded in them. The profile presenter (125) walk both the text and these embedded COM controls using COM (also known as OLE or ActiveX programming) to determine where the user is currently entering text (ignoring any other text or embedded controls before or after the current email address) so that the profile presenter (125) can correctly determine where the current user's entry begins and ends, what text to use to create suggestions for, and also which part of the text (or embedded controls) to replace.

In one embodiment, the profile presenter (125) uses a person-centric approach to identify the suggestions. The partial input (e.g., “Graf” received in the entry box (203)) is used to match the names of the persons to identify the persons in the profile set (113) (e.g., the first name, the last name, the nickname, etc.). The profile presenter (125) sorts the matched persons based on a relationship score determined from the statistical data derived at least in part from the received messages (115) and the sent messages (117).

FIG. 6 shows a method to select suggestions to complete address input according to one embodiment.

In FIG. 6, after receiving (231) one or more letters that are typed in by an end user in an entry box configured to receive an address for an outgoing message, the profile presenter (125) determines (233) whether the one or more letters match part of a name in the profile set (113). If there is a match (or more than one match), the profile presenter (125) retrieves (235) the addresses associated with the matched name(s), sorts (241) the addresses, and presents (243) the addresses for selection in suggestion window (205).

In FIG. 6, if there is no name that matches the one or more letters, the profile presenter (125) determines (237) whether the one or more letters match part of an address in the profile set (113). If there is a match (or more than one match), the profile presenter (125) retrieves (239) the matched address(es), sorts (241) the addresses, and presents (243) the addresses for selection in suggestion window (205).

Thus, the user can input the names of the recipient to cause the profile presenter (125) to identify the persons with names matching the input to select the person and thus select the address of the person. The names of the recipient do not have to be part of the addresses to be matched and suggested.

In one embodiment, when a person has multiple addresses, the suggestion window (205) shows multiple suggestions for the addresses presented with the name of the person.

In another embodiment, when a person has multiple addresses, the suggestion window (205) shows one entry to suggest the person. If the person is selected, the suggestion window (205) is then updated to show a list of addresses of the person. If the user selects one or more addresses, the profile presenter (125) replaces the name of the person with the selected address(es) of the person; if the user does not select any of the multiple addresses, the profile presenter (125) replaces the name of the person with all of the multiple addresses. In one embodiment, if the user does not select any of the multiple addresses of the person, the profile presenter (125) replaces the name of the person with the top ranked address of the person in the To field and inserts the other addresses of the person in the CC or BCC field (or uses the top ranked address without using the other addresses of the person).

In FIG. 6, the profile presenter (125) attempts to first match names of the persons in the profile set (113) and, if there is no match in names, then match addresses of the persons in the profile set (113).

In another embodiment, the profile presenter (125) may perform a search to match the beginning of a number of fields in the profile set (113), such as, different fields of names of the persons in the profile set (113), different segments of email addresses of the persons in the profile set (113), the names of cities (or states or countries) of the persons in the profile set (113), different words in the street addresses of the persons in the profile set (113), different words of job titles of the persons in the profile set (113), screen names of the persons in the profile set (113), etc. Examples of different fields of names include first name, last name, middle name, nick name, etc. Examples of different segments of email addresses include segments or chunks of an email prefix separated by a separator, such as “−”, “.”, or “_”, different levels of domain names of an email address, etc. In some embodiments, the names of the persons are as part of the email addresses. In some embodiments, the names are from fields separated from the email addresses.

When the profile presenter (125) searches different types of fields, a match in different types of fields may be weighted differently. For example, a match in a name field may be given a first weight (e.g., 10), a match in an email prefix segment may be given a second weight (e.g., 8), a match in the top level domain name may be given a third weight (e.g., 1), and a match in other domain names (e.g., second level domain name, or lower level domain names) may be given a fourth weight (e.g., 2), etc. When a person or an address has multiple matches in different fields, the weights for the multiple matches may be added to compute the weight for the person or address. Alternatively, the highest weight for the multiple matches can be selected as the weight for the person or address. The weights for the matched persons or addresses can be used to sort the persons or addresses for selection of up to a predetermined number of suggestions for presentation to the user. For example, the weights can be applied to the relevancy scores of the matched persons or addresses to determine relevancy scores for suggesting the persons or addresses; and the profile presenter (125) selects up to a predetermined number of matched persons or addresses that have the highest relevancy scores for suggesting the persons or addresses.

In FIGS. 4 and 5, the suggestions presented based on the profile set (113) are shown as a list of entries, where a typical entry includes the name and the address of the person. However, in other embodiments, the entries may further include other information, such as a photo image of the person, a job title of the person, a business association of the person, etc. In some embodiments, other details of the profile of the person are shown in a separate window when the cursor is positioned and remains positioned on the entry for the person (e.g., hovering over the entry).

In one embodiment, the profile presenter (125) ranks the persons for the suggestions to complete the address input, based on the relevancy index between the suggested persons and the user of the user terminal (101). When dealing with long lists of contacts, such a relevancy index helps users find the most relevant contacts first.

In one embodiment, the profile builder (119) scans the messages (115 and 117) to capture the addresses of the senders and recipients of the messages (115 and 117). Each of the captured addresses is stored in an index file. When one of those addresses is seen in a header that describes the recipients and senders, the score for the address is increased by a predetermined amount (e.g., 1). In some embodiments, the profile builder (119) further scans the body of the messages (115 and 117) to identify additional addresses.

In some embodiments, different weights/amounts are given to the score when the addresses are used in different fields (e.g., From, Reply-To, To, CC, and BCC fields of emails). For example, an amount of 3 may be given to the score when an address is found in a field that identifies the sender of the message (e.g., From or Reply-To fields of emails received by the user of the user terminal (101)); and an amount of 1 may be given to the score when the address is found in a field that identifies the recipient of the message (e.g., To, CC, and BCC fields of emails sent from the user of the user terminal (101)).

In some embodiments, the same amount is given to the score regardless of the type of fields in which the address is used (e.g., From, Reply-To, To, CC, and BCC fields of emails).

In some embodiments, the length of the elapsed time period since receipt of the message is further used to determine the amount given to the score. The occurrence of an address in a recent message can be given more weight than the occurrence of the address in a message received/sent earlier than the recent message.

Thus, after the messages (115 and 117) are processed, each of the addresses has a relevancy score. The higher the score, the more relevant the address is to the user of the user terminal (101).

In some embodiments, the relevancy score is computed from the data in the profile (131), such as the total number of messages received from the person (148), the total number of messages sent to the person (149), etc. In some embodiments, the number of messages are counted based on the types of fields in which the addresses appear and the time periods in which the messages are sent or received.

In one embodiment, the profile builder (119) further groups the addresses by the names of the corresponding persons. Each person having a name in the profile set (113) may have one or more addresses. In one embodiment, the scores for the addresses of the person are summed to generate a score for the person. Thus, the higher the score, the more relevant the person is to the user of the user terminal (101).

In one embodiment, when the suggestions are presented as a list of addresses, the scores for the addresses are used to sort the addresses. When the suggestions are presented as a list of persons, the scores for the persons are used to sort the list of names of the persons.

In another embodiment, the suggestions are presented as a list of addresses grouped according to the persons. The addresses for each person are grouped together and sorted within the group based on the scores of the emails. The groups are sorted according to the scores of the persons.

In one embodiment, the profile presenter (125) selects up to a predetermined number (e.g., 10) of candidates, after sorting the candidates for the suggestions based on the relevancy scores. The selected candidates are presented in the suggestion window (205) to help the user. Less relevant candidates are not presented in the suggestion window (205).

While some of the embodiments are discussed here in the context of composing an email message, the techniques disclosed here can also be applied to the specifying of address information for instant messaging, text messaging, dialing a phone number, etc. Instead of matching the incomplete input to the exact address, the profile presenter (125) can match the incomplete input with identifiers of the persons in the profile set (113) to identify the persons as the basis for suggestions. Examples of identifiers include nickname, first name, last name, company name, domain name, user name, screen name, phone number, etc. In one embodiment, the suggestions are searched and presented in the form of suggested persons and thus, the suggestions are person-centric.

In some embodiments, the user terminal (101) may include different communication components that require address information for different types of communications, such as email, instant messages, text messages, phone calls, etc. The profile presenter (125) may use the profile set (113) to generate the suggested candidates for completing an address input for the different types of communications.

In some embodiments, the relevancy score is computed for the person without considering the type of communications. In other embodiments, the addresses having the same type as the address to be suggested are given more weight than other types of addresses. For example, when ranking the persons for suggesting addresses for instant messaging, the addresses for instant messaging may be given more weight than addresses for other types of communications, such as email, phone calls, etc. Thus, for different types of communications, the profile presenter (125) may suggest different lists of persons based on the same profile set (113) and the same incomplete input.

FIG. 7 shows a method to provide address assistance according to one embodiment. In FIG. 7, the profile builder (119) scans (251) a set of messages (115 and 117) to identify addresses of senders of the messages and addresses of recipients of the messages in an automatic way, for example, when the profile builder (119) is installed and/or when the messages (115 and 117) are received or sent.

The profile builder (119) identifies (253) the names of persons at the addresses to create profiles (131) for the persons, based on scanning the messages (115 and 117) and/or querying other data sources in an automated way, such as the web search engine (163), online directory (164), social network server (165), and other websites.

In one embodiment, the profile builder (119) computes (255) a relevancy score for each of the addresses based on a number of messages in which the addresses are used and types of fields in which the addresses are used in the messages. For example, instances where an address is used to specify a recipient of a message sent from the user of the user terminal (101) may be given more weight than instances where the address is used to specify a sender of a message received by the user of the user terminal (101).

In one embodiment, the profile builder (119) also computes (257) a relevancy score for each of the persons based on the relevancy score of the addresses of each person.

In FIG. 7, in response to an incomplete input in an address field, the profile presenter (125) identifies (259) a set of persons by matching the incomplete input with names of the persons and/or the addresses of the persons. The profile presenter (125) sorts (261) the addresses of the identified persons according to the relevancy scores of the persons and/or the relevancy scores of the addresses, and selects and presents (263) up to a predetermined number of suggestions from the sorted addresses. In response to a user selection of one of the suggestions, the profile presenter (125) replaces (265) the incomplete input with the user selected address.

FIG. 8 shows a data processing system, which can be used in various embodiments. While FIG. 8 illustrates various components of a computer system, it is not intended to represent any particular architecture or manner of interconnecting the components. Some embodiments may use other systems that have fewer or more components than those shown in FIG. 8.

In one embodiment, the user terminal (101) can be implemented as a data processing system, with fewer or more components, as illustrated in FIG. 8. When one or more components of the user terminal (101) are implemented on one or more remote servers, the servers can be implemented as a data processing system, with fewer or more components, as illustrated in FIG. 8.

In FIG. 8, the data processing system (301) includes an inter-connect (302) (e.g., bus and system core logic), which interconnects a microprocessor(s) (303) and memory (308). The microprocessor (303) is coupled to cache memory (304) in the example of FIG. 8.

The inter-connect (302) interconnects the microprocessor(s) (303) and the memory (308) together and also interconnects them to a display controller, display device (307), and to peripheral devices such as input/output (I/O) devices (305) through an input/output controller(s) (306).

Typical I/O devices include mice, keyboards, modems, network interfaces, printers, scanners, video cameras and other devices which are well known in the art. In some embodiments, when the data processing system is a server system, some of the I/O devices, such as printer, scanner, mice, and/or keyboards, are optional.

The inter-connect (302) may include one or more buses connected to one another through various bridges, controllers and/or adapters. In one embodiment, the I/O controller (306) includes a USB (Universal Serial Bus) adapter for controlling USB peripherals, and/or an IEEE-1394 bus adapter for controlling IEEE-1394 peripherals.

The memory (308) may include ROM (Read Only Memory), volatile RAM (Random Access Memory), and non-volatile memory, such as hard drive, flash memory, etc.

Volatile RAM is typically implemented as dynamic RAM (DRAM) which requires power continually in order to refresh or maintain the data in the memory. Non-volatile memory is typically a magnetic hard drive, a magnetic optical drive, an optical drive (e.g., a DVD RAM), or other type of memory system which maintains data even after power is removed from the system. The non-volatile memory may also be a random access memory.

The non-volatile memory can be a local device coupled directly to the rest of the components in the data processing system. A non-volatile memory that is remote from the system, such as a network storage device coupled to the data processing system through a network interface such as a modem or Ethernet interface, can also be used.

Making Relationships Universally Available Across Applications

In one embodiment, the detection of a predefined user motion (e.g., a motion by a user on a trackball or other interface item) can be implemented on a user device (for any of numerous types of user devices or platforms) so as to provide a universal, contextual access to relevant relationships based on modality (state awareness).

In alternative embodiments, the providing of universal, contextual access to relevant relationships is not necessarily based on user motion, but may be based on other operational or state characteristics of a user device (e.g., the user account being used to compose and/or send an email message). These characteristics may also include data obtained from sensors or systems associated with or operating on the user device. Various embodiments related to predefined user motions and use of user context in selecting or suggesting input for the user are described in U.S. Provisional Application Ser. No. 61/349,162, filed May 27, 2010, entitled “PRESENTING A NEW USER SCREEN IN RESPONSE TO DETECTION OF A USER MOTION,” by Michael Holzer, which was incorporated by reference above.

For example, while on a call (e.g., using a mobile or desktop/Cisco IP phone), a user request for personal information (e.g., user profile or relationships data) presents additional data regarding the caller and the company. The user device also may show additional information about likely-related contacts (e.g., in this case, people that the user most likely would desire to add for a planned conference call). The state awareness simplifies the user interface by reducing the keystrokes/gestures required to perform the most typical or common follow-on tasks. The user's actual use and behavior with the user device is more efficient due to the easier access to relevant data (e.g., recent contacts, upcoming appointments, alternate contact data, etc.).

For example, reading email, and checking the people in the thread and their relationship to the user are more efficiently performed (this efficiency in usage also applies to related items, like conversations and attachments exchanged). In a customer relationship management (CRM) or similar application, the state aware interface reduces the address book data for selecting a contact or adding a contact to a small subset of the total available data based on other information in the application. So, as a user is working on its, for example, “Cisco account”, the subset of people that are offered/favored to the user via the device interface are a ranked list of Cisco contacts, optionally including a relevance filter on the actual topic relevant to the current user task. This is useful when, for example, the user has information stored in the user device for tens or hundreds of contacts within a given topic or other subject area (e.g., by company, geographic location, etc.).

The presence on the user device of an overlay of contextually-related relationships that is available to the user at any point in navigating or using the user device is helpful to the user. For example, if the user is on the phone in a live conversation, and simply uses a particular, predefined trackball motion on a home screen, the user device may show the user a ranked list of people that the user is likely to be dealing or interacting with based on various forms of data collected or accessible by the device (e.g., geographic data, calendar data, time of day, items and data in the user's “in” box, etc). The list of most likely information desired or needed by the user is a significantly smaller subset (e.g., in the tens of persons) when compared to the total available relationships stored on the user device (e.g., which may be in the thousands of persons).

For example, an overlay of relationships across applications may be now described with respect to a BlackBerry user device. When the user is composing an email, an upwards trackball motion provides the user with relatively quick access to those persons the user might need to send an email. The user interface is made smarter by any input the user may have provided (e.g., subject, body, other recipient, or prior activity like a recent phone call). This analysis is independent of the core application. The person relationships are carried universally across the user device platform and offered for use by any of the applications that may be running on the platform.

This may be implemented similarly to the manner in which printing services are offered to all applications on a personal computer. In some embodiments, the application itself may modify or customize the implementation of the printing option. For example, a label printing application may provide formatting for label printing (even though the printing is handled universally by the operating system (OS) or a service that runs in addition to the application itself).

The application itself may allow for the service to be invoked. In this example, the user indicates it has an account with a third party service provider (e.g., the Xobni service), and then the service provider's computer systems interact with the application to supplement the application. For example, the application does not need to be integrated at the OS or device level.

Sender-Based Ranking and Time-Decay

In some embodiments, ranking of persons by profile presenter 125 may apply time-decay factors to decrease the weight given to one or more messages when computing a relevancy index or score for a particular person. Also, alternatively or in combination with such time-decay factors, when profile builder 119 is scanning messages, the weight associated with any given message may be made greater if the message has been sent by the user (and the weight may be made less for messages received by the user). In one embodiment, the message may be given no consideration or a zero weight if the message has been received by the user, as contrasted with having been sent by the user (i.e., only messages sent from the user are used for determining a relevancy score).

The sender-based and/or time decay ranking of persons described above may be used in various applications. For example, one application is the sorting of results presented to a user in reply to a search request (e.g., a user request to search a large number of person profiles previously built by profile builder 119). Another application is the use of these rankings to present suggestions to the user for automatic completion on an input (e.g., a recipient field in a message or a calendar invitation).

A specific exemplary embodiment is now discussed in more detail. In this embodiment, the ranking of persons is (a) time-decayed and (b) sender-weighted, as follows:

a. Time-decayed weighting: If a user sent a person John 100 messages last year, but the user sent person Frank a few messages this week, the ranking of the person Frank will be higher than that for the person John, if based solely on this time-decay factor.

b. Sender-based weighting: If the person John sent to the user hundreds of emails, but the user never (or rarely) replied, the person John is ranked lower than someone that the user sends messages to more frequently. This is based on a typical expectation that the recipient is more important (more relevant) to the user if the user makes an effort to write to the person. This approach may in some cases also reduce the number of spammers and mailing lists that receive a higher ranking (e.g., based merely on a very large number of spam messages or junk mail sent to the user terminal).

The time-decaying and sender-weighting factors may be used alone, or in combination (e.g., combined based on equal or different weightings for each approach). In one embodiment, the time-decaying factors are implemented by maintaining a histogram (e.g., stored on the user terminal). One histogram is maintained for each person having a person profile stored on the user terminal.

This histogram is an array of buckets, with each bucket holding a number of occurrences. For example, the histogram may have 52 buckets, with the first bucket indicating the number of emails the user sent to a specific recipient this week, the next bucket indicating the number sent to that same recipient last week, etc. Overall, a week's worth of counts are contained in each of the 52 buckets. The last bucket may be used for messages sent or received 52 weeks ago or beyond to even earlier dates. Each week, the numbers in the buckets may be slid over one week to the right in the histogram.

Once this histogram is created or updated, it provides a vector of numbers, one for each bucket. In one embodiment, a vector of weights is multiplied with the histogram vector (e.g., a first bucket number of occurrences is multiplied by a first vector weight, etc.,). In other words, the vector of weights is multiplied pair-wise with the number of occurrences in each bucket of the histogram. The resulting multiplication products are added together to get a total score for a given person (this operation is commonly called a “dot product”). This score may be stored in the person profile.

As another example, all emails used to calculate a rank for persons are stored on the user terminal and are associated with a first email account of the user. Some of the emails were sent by the user and some were received by the user from one or more of the persons. In one case, only the emails that were sent by the user are added to the histogram. The emails received by the user are identified and ignored in the rank calculation. In other cases, there is a hybrid mix of emails sent and emails received, with emails sent by the user receiving a higher weighting.

The ranking may be implemented as a point or scoring system. For example, if a user sends a recipient an email today, that gives the recipient one point in this ranking system. If the user sends another email to the recipient today, then the recipient has a score of 2 points. Over time, these point values will decay based on the histogram and time-decaying factors discussed above. For example, a year from now each point may have decreased to a score of only 2/100ths of a point.

Specific User Account

The time-decayed and sender-weighted factors discussed above may further be combined or used with a user account-specific factor. This account-specific factor also may be used with, for example, automatic completion suggestions or ranking of search results when searching persons on a user terminal, as was discussed above.

As an example of the account-specific factor, if a user starts adding a recipient to an email by typing “J . . . ” when the user is using a home email account (e.g., when located on a home-based desktop computer, or when logged into a mail account that the user typical uses for personal email), the user likely intends to send the email to the user's friend John. In contrast, if the user starts this same typing (i.e., “J . . . ”) using a work email account (e.g., when located at work, or when at home but using the work email account), the user likely intends to send the email to the user's boss Jeff.

In order to properly rank the most likely recipient above based on the user email account that is used to compose and send the email, email client software determines the particular user email (or other messaging system) account that is being used as the sender information when composing a new message. This user account is then used, for example, as one factor along with time-decay and/or sender-weighting factors (in any desired combination) to determine a score for the persons. It should be noted that many email clients such as Microsoft's Outlook and Google's Gmail allow the user to choose from among several email accounts when sending an email, so that the email will appear to a recipient to have been sent from that account. In one embodiment, this user choice of email accounts is taken into account for the account-specific ranking.

For example, each person profile may contain information about the user account (e.g., user@jet.com) used to send prior emails to that person. If there is a match of a user account field (e.g., a match to “jet.com” or simply “jet”) in the person profile to the user account name currently being used to compose, or associated with the sending of the new email, then the score of this person is increased for presentation of auto-complete suggestions in this email. In an alternative embodiment, instead of detecting a user account in an email being composed, an identifier of the user terminal or device being used to compose the message could be used instead of the user account name. In other embodiments, both the device identifier and the user account may be used in determining a rank or score of persons.

When using this specific-account factor with time-decay factors, in one embodiment a histogram may be used for each user account. Thus, there are two histograms for a first person and two histograms for a second person (e.g., the first histogram for the first person corresponds to a first user account, and the second histogram for the first person corresponds to a second user account).

In other embodiments, additional histograms may be used including a generalized histogram that is for the sending of a message to a recipient, regardless of the user account used to send the message. This generalized histogram would be a combination of the two account-specific histograms. This generalized histogram may be used if a specific user account cannot be identified.

Multi-Person Automatic Suggestions

In one embodiment, a method includes scanning a set of messages (e.g., emails stored on a user terminal) to build a set of person profiles, as discussed above. Also as discussed above, scores of persons may be computed using data in these person profiles to determine the relevancy of the persons to the user. Search results or suggestions presented to the user may be ranked or sorted based on these scores. A user provides input (e.g., by typing) in a recipient name or address field (e.g., a “To:” or “CC:” field) of a new message that is being composed. After a first person is so selected to be a recipient of the message, the user may select a second person to be a recipient. The user terminal presents to the user, in an order determined by the sorting, one or more suggestions for an additional recipient name or address (corresponding to this second person) to add to the message. The sorting is done using computed scores. It should be noted that these computed scores are different from the computed scores discussed in prior sections above. More specifically, in one embodiment, the computed scores in the prior sections above rank the likelihood of the user sending email to each of his/her contacts, without any additional context. Here, the computed scores rank the likelihood of the user sending email to each of his/her contacts given the fact that one or more specific contacts have already been specified as recipients of the email message.

In one embodiment, the person profiles contain prior associations between persons that have been observed or otherwise determined (e.g., via social network or social graph data) so that the score may include a factor or component due to these associations.

As one example, an auto-suggestion list of potential recipients pops up when the user is composing an email. If a new email is started, and “John Smith” has already been added to the “To:” field, the user terminal presents a list of other persons that are typically also included on messages along with John Smith. The persons on this list are ranked based on a computed score (e.g., including sender-based and time-decay factors as discussed above). Again, it should be noted that this computed score is different from the computed scores discussed in prior sections above (however, this different score may be computed in one embodiment using the same sender-based, time-decayed methodology as was discussed above). Again as mentioned above, here the computed scores rank the likelihood of the user sending email to each of his/her contacts given the fact that one or more specific contacts have already been specified as recipients of the email message.

So, once a first person is added as a recipient, other persons that are usually included as a recipient (e.g., as “To:” or “CC:” recipients) along with the first person are presented as suggestions to the user. This approach may be extended to the suggestion of yet a third person based on the prior entry or adding of first and second persons as recipients.

In one embodiment, the ranking of persons does not include every person in person profiles stored on the user terminal. Instead, the ranking is limited to those persons that the user might include on an email along with the first person that has already been entered. Prior associations between email addresses or other communication endpoints (e.g., stored on the user terminal) are used to perform this ranking. This provides a contextual suggestion of other persons that the user may desire to include on this new message.

As an extension of the above multi-person feature, in some embodiments the topic, content, and/or specific text included in the subject line or body of a message may be used to as yet a further factor to computer scores for ranking persons most likely to be intended recipients of an email or other message that is being composed. Prior associations of topics, content, and/or text as stored in the person profiles on the user terminal may be used in the ranking computations.

In one example, if a user is sending an email to John and Eric, the user is probably discussing billing matters. If the user is sending an email to John and Bruce, the user is probably talking about a messaging architecture. In each case a topic is identified from the new email being composed or from topic data stored in person profiles for John and Eric, or John and Bruce. This identified topic is then compared to other person profiles to rank persons for suggesting another potential recipient of the message. If the user is emailing John and Eric, one list of persons is presented. If the user is emailing John and Bruce, then a different list of people is presented.

In some embodiments, the use of the above multi-person factor may be combined with other factors discussed above such as the account-specific, time-decay, and/or sender-weighted factors. Also, time or calendar information (such as obtained from a calendar and/or clock on the user terminal) may be used in addition to the foregoing to select persons for ranking (e.g., if the user terminal determines that the user has a meeting with a person in 10 minutes, and the user starts an email to the first letter of that person's name, then the user terminal gives a high weighting to this factor as it is likely the user intends to send an email to a person at that meeting). The name of the first person added to the email may be done by typing or by selecting from a scroll-down or pull-down list.

In addition, once a first person is determined to be associated with a meeting or other calendar event, the above multi-person approach (and further optionally in addition the above topic/content/specific text approach) may use associations to this first person in order to rank suggestions of yet other persons to present to the user as automatic completion suggestions.

Closing

In this description, various functions and operations may be described as being performed by or caused by software code to simplify description. However, those skilled in the art will recognize that what is meant by such expressions is that the functions result from execution of the code/instructions by a processor, such as a microprocessor. Alternatively, or in combination, the functions and operations can be implemented using special purpose circuitry, with or without software instructions, such as using Application-Specific Integrated Circuit (ASIC) or Field-Programmable Gate Array (FPGA). Embodiments can be implemented using hardwired circuitry without software instructions, or in combination with software instructions. Thus, the techniques are limited neither to any specific combination of hardware circuitry and software, nor to any particular source for the instructions executed by the data processing system.

While some embodiments can be implemented in fully functioning computers and computer systems, various embodiments are capable of being distributed as a computing product in a variety of forms and are capable of being applied regardless of the particular type of machine or computer-readable media used to actually effect the distribution.

At least some aspects disclosed can be embodied, at least in part, in software. That is, the techniques may be carried out in a computer system or other data processing system in response to its processor, such as a microprocessor, executing sequences of instructions contained in a memory, such as ROM, volatile RAM, non-volatile memory, cache or a remote storage device.

Routines executed to implement the embodiments may be implemented as part of an operating system or a specific application, component, program, object, module or sequence of instructions referred to as “computer programs.” The computer programs typically include one or more instructions set at various times in various memory and storage devices in a computer, and that, when read and executed by one or more processors in a computer, cause the computer to perform operations necessary to execute elements involving the various aspects.

A machine readable medium can be used to store software and data which when executed by a data processing system causes the system to perform various methods. The executable software and data may be stored in various places including for example ROM, volatile RAM, non-volatile memory and/or cache. Portions of this software and/or data may be stored in any one of these storage devices. Further, the data and instructions can be obtained from centralized servers or peer to peer networks. Different portions of the data and instructions can be obtained from different centralized servers and/or peer to peer networks at different times and in different communication sessions or in a same communication session. The data and instructions can be obtained in entirety prior to the execution of the applications. Alternatively, portions of the data and instructions can be obtained dynamically, just in time, when needed for execution. Thus, it is not required that the data and instructions be on a machine readable medium in entirety at a particular instance of time.

Examples of computer-readable media include but are not limited to recordable and non-recordable type media such as volatile and non-volatile memory devices, read only memory (ROM), random access memory (RAM), flash memory devices, floppy and other removable disks, magnetic disk storage media, optical storage media (e.g., Compact Disk Read-Only Memory (CD ROMS), Digital Versatile Disks (DVDs), etc.), among others. The computer-readable media may store the instructions.

The instructions may also be embodied in digital and analog communication links for electrical, optical, acoustical or other forms of propagated signals, such as carrier waves, infrared signals, digital signals, etc. However, propagated signals, such as carrier waves, infrared signals, digital signals, etc. are not tangible machine readable medium and are not configured to store instructions.

In general, a tangible machine readable medium includes any apparatus that provides (i.e., stores and/or transmits) information in a form accessible by a machine (e.g., a computer, network device, personal digital assistant, manufacturing tool, any device with a set of one or more processors, etc.).

In various embodiments, hardwired circuitry may be used in combination with software instructions to implement the techniques. Thus, the techniques are neither limited to any specific combination of hardware circuitry and software nor to any particular source for the instructions executed by the data processing system.

Although some of the drawings illustrate a number of operations in a particular order, operations which are not order dependent may be reordered and other operations may be combined or broken out. While some reordering or other groupings are specifically mentioned, others will be apparent to those of ordinary skill in the art and so do not present an exhaustive list of alternatives. Moreover, it should be recognized that the stages could be implemented in hardware, firmware, software or any combination thereof.
